Title: Improvements in hydraulic turbine runner blading
IPC: B23D3/04
Filed: 1923-04-05
Abstract: 201,523. Moody, L. F. July 29, 1922, [Convention date]. Shaping helical surfaces; boring and turning mills.-Runner-blades for hydraulic turbines are given contours of relatively simple geometrical form, thus enabling them to be automatically shaped by a simple mechanism such as a lathe or boring mill. In an arrangement for machining the blades of an axial flow turbine shown in Fig. 1, the runner is mounted on a rotatable mandrel 3, which is oscillated to carry a cutting tool 5 across a blade, the tool being simultaneously oscillated in a vertical plane by a worm 7, geared to the mechanism for moving the mandrel and meshing with a toothed sector 6. The tool-carrier 9 is fed bv a screw 11 after each cut and as the length of its cut is therefore progressively increased, the pitch of the blade increases from the tip towards the hub. The helicoidal form thus produced may be further varied bv a special former, such as a cam 13 on the mandrel 3 which displaces the slide 12 on which the work is mounted. In the Specification as open to inspection other means for machining blades of various forms are described as follows:-In the machine of the diagonal inward flow blades 4' shown in Fig. 2 (Cancelled) the tool is reciprocated along straight lines by mechanism geared with the mandrel and the form produced is a helicoid of constant pitch. In the production of blades of conical section a blade 21 with a section 23<1> of the sectional hub is mounted in a mandrel 25 supported on wedge blocks 27 on the turn-table of a boring-mill so that the runner axis r, r is inclined to that of the table and the turn-table is oscillated or rotated. Or the blades 21 and their hub-sections 21<1> mav be held in a special fixture on the table at the desired angle as shown in Fig. 11 (Cancelled) and machined simultaneously by a rotary movement. This subject-matter does not appear in the Specification as accepted.

Abstract: 324,574. Haupt, H. March 25, 1929. Holding open and closed.- An umbrella with a movable member 6, Fig. 1, for releasing the spring catch 3 holding up the runner 2 in the open position, is characterized in that both the spring catch and the movable member are lodged in slots provided in a solid stick 1. The movable member 6 is constructed as a hollow bar, Fig 2, guided in a slot or notch 5 in the stick. The upper end of the member 6 is' slotted at 7 to accommodate the spring catch 3. Upward movement of a ring S adjacent the handle 9 forces the end 12 of the bar 6 already within the runner 2 further upwards, the bar 6 depressing the catch 3 so as to release the runner 2 allowing the umbrella to close. The bar 6 is returned by a spring 11. The bar 6 has a cone 13 bearing upon the spring catch 3 to prevent the edge of the slot 7 chafing on the catch. The bar is guided on the stick on a pin 14 extending transversely of the stick and on a wire 15. The umbrella is assisted to close by a slotted spring 21, Fig. 6, fitted to the runner 2 which presses on the ends of the struts 24. A spring ring 59 also assists in this operation.

Title: Improvements in the manufacture of sulphate of ammonia
IPC: C01C1/247
Filed: 1930-05-30
Abstract: 356,757. Electrolysis. HODSMAN, H. J., 2, Norwood Grove, Victoria Road, Headingley, Leeds, and TAYLOR, A., 176, Victoria Avenue, Hull. May 30, 1930, No. 9543/31. Divided application. [Class 41.] Ammonium sulphate is produced by electrolytic oxidation of an aqueous solution of ammonium sulphite in the presence of a soluble chloride preferably ammonium chloride. The ammonium sulphite solution may be prepared by absorbing sulphur dioxide in crude ammonia liquor and may be previously partially oxidized by means of gases containing free oxygen, preferably in the presence of catalysts. The presence of the chloride is particularly beneficial when oxidizing solutions containing below 4 per cent of ammonium sulphite. A concentration of 4 per cent of ammonium chloride is suitable. This proportion is normally present when the electrolyte has been prepared from crude ammonia liquor. Ammonium or sodium chlorides may be added, if necessary. The electrolyte may be agitated, e.g. by a rotating electrode ; diaphragms are not employed. A suitable current density is 0À6 amps. per sq. dcm. at 0À35 volts. The electrodes may consist of bundles of carbon rods supported by brass frames. The electrolysis is arrested before any thiocyanate or thiosulphate which may be present is oxidized. It is then partially evaporated, sulphate of ammonia, containing some chloride, crystallizing out. Specification 356,283 is referred to.

A process for making foamed ethylene copolymers comprises mixing a molten thermoplastic ethylene copolymer with isobutane or a C 5 _ 7  hydrocarbon having at least 2 lateral methyl groups and a b.pt. of - 10‹ to 60‹ C. in an amount of 5-35 parts per cent by weight with reference to weight of polymer at a pressure above the vapour pressure of the latter at the mixing temperature and flashing to reduced pressure. The preferred hydrocarbons are 2,2- dimethylpropane, 2,2-dimethylbutane and 2,3- dimethylbutane, the first two being employed in the examples wherein ethylene copolymers with n- and t.-butyl acrylate, vinyl acetate and 2-hexylacrylate are foamed. Foams with fine cell structure may be produced by incorporating nucleating agents such as talc or substances which release gases on heating, such as azo compounds or sodium bicarbonate/citric acid mixture. Mixtures of ethylene copolymers with other polymers may be foamed, e.g. ethylenevinyl acetate copolymer with polyisobutylene. Bitumen may also be incorporated in the material to be foamed.
